Mono Sulfur Silane Crosile^® 966 for high loading Silica tire

Lower rolling resistance with retained wet traction for high-loading silica tire treads.

Product Description

Crosile^® 966 is a Mono Sulfur silane that can reduce rolling resistance while maintaining wet traction. Compared to conventional silane coupling agents like Crosile 69 and Crosile 75, Crosile 966 offers superior processing performance and can improve the overall production efficiency of tires.

Key Features

Mono Sulfur Silane Coupling Agent

High-performance organosilane for silica-rich tire tread compounds, added in a single step.

Strong Filler–Rubber Network

Generates a strong filler–rubber network with an enhanced Payne effect.

High-Loading Silica Compatible

Compatible with ≥ 80 phr silica without loss of scorch safety.

Performance Improvement

Lower Rolling Resistance: Drops tan δ 50–60 °C by 15–25 %, achieving ≥ 4 % reduction in RRC (rolling-resistance coefficient).

Winter & Wet Performance: Dynamic modulus advantage from –20 °C to +10 °C shortens braking on cold/wet roads, while tan δ @ 0 °C preserves wet grip.

Processing Efficiency: Acts as an internal silica dispersant for 10–15 % lower Mooney viscosity; shortens mixing cycles, improves extrusion surface and reduces die-build-up.

Eco-Friendly & VOC Reduction: One-shot addition eliminates multi-step mixing, cutting VOC emissions and energy use.

Application Scenarios

Passenger-Car Green Tires

Passenger-car green tires demanding < 7 kg t-1 CO₂ savings.

All-Season & Winter Compounds

All-season and winter compounds requiring winter-grade elasticity and wet traction.

HP/UHP Segments

HP/UHP segments needing A-grade wet grip with low rolling resistance.

Packaging And Transportation

Packing: Packed in plastic drums, with a net weight of 25 kg per drum.
Storage: Store in a cool, ventilated, and dry place.
Shelf life: One year under normal storage conditions.
